A Honda Civic and Lincoln Town Car are initially at rest on a horizontal parking lot at the edge of steep cliff. The Town Car has twice as much mass as the Civic. Equal constant forces are applied to each car and they accelerate across equal distances (ignore effects of friction.) When they reach the far end of the lot the force is suddenly removed, whereupon they sail through the air and crash on the ground below.
1.) Which has the greater acceleration?
**I think the civic car because the town car has doubled mass and when mass is doubled, the acceleration is halved so the Civic has a greater acceleration because of a smaller mass.**
2.) Which car spends more time along the surface of the lot, the faster or slower one?
**the slower car spends more time, which is the town car because it is not accelerating as fast as the civic.**
3.) Which car lands farthest horizontally from the edge of the cliff onto the ground below?
**I think the civic car lands farther because it has less mass so it will be able to go out more and it's accelerating more then the town car, which has more mass and will fall before closer to the lot then the civic!**
4.) Which car spends more time in the air from the edge of the cliff to the ground below?
**the civic car spends more time in the air because it's mass is not as great as the town cars and it takes it longer to reach terminal speed so it spends more time in the air.**

What did Galelio prove by dropping a massive and a light ball at the same time in Pisa? I suspect terminal velocity is not a consideration here, nor friction due to air.
